Handcarved blades tipped with stainless steel? Ball bearings? Gears? Feathering mechanisms? Nope. A few boards and lots of “American Ingenuity” (for which this country is justly famed) make practical working machines that pump, saw, and in later times generate electricity. This paper was originally published in the 1890s and it’s a real eye-opener. Funky, yes. Down-home, for sure. And it may well cause more people to make working machines than any windpower book yet published. Interesting sociologically, too.
